Non Technical Summary
As a building material, wood fails because it gets wet. Wood exhibits swelling upon moisture uptake and shrinkage upon drying, and these cyclical moisture changes lead to internal stresses and can eventually form splits and checks within the wood. When there is an abundance of moisture in the wood, it is susceptible to microbial growth, fungal decay, corrosion of embedded metals, and chemical depolymerization from certain ions and free radicals. This problem area examines how and why wood in buildings gets wet so that better construction practices can be developed.


Objectives Summary
The objective of this problem area is to understand how changes in how the building envelope is constructed lead to moisture accumulation in the wood, and how accumulated moisture can lead to wood failures.


Approach Summary
• Field testing- monitoring moisture in wood buildings• Characterization- characterizing the hygrothermal properties of building materials• Modeling- using climatic data and accurate material properties to predict moisture accumulation in buildings• Laboratory scale tests of new wall assemblies- performed at the one-of-a-kind Chamber for Analytic Research on Wall Assemblies Exposed to Simulated Weather (CARWASh).
